| NASA's Spitzer finds distant galaxies grazed on gas Posted: 30 Jun 2011 01:24 PM PDT Galaxies once thought of as voracious tigers are more like grazing cows, according to a new study using NASA's Spitzer Space Telescope. Astronomers have discovered that galaxies in the distant, early universe continuously ingested their star-making fuel over long periods of time. This goes against previous theories that the galaxies devoured their fuel in quick bursts after run-ins with other galaxies.  |
| 'Zombie' stars key to measuring dark energy Posted: 30 Jun 2011 10:18 AM PDT "Zombie" stars that explode like bombs as they die, only to revive by sucking matter out of other stars. According to an astrophysicist, this isn't the plot for the latest 3-D blockbuster movie. Instead, it's something that happens every day in the universe -- something that can be used to measure dark energy.  |
| The future of chip manufacturing Posted: 30 Jun 2011 08:29 AM PDT Researchers have shown how to make e-beam lithography, commonly used to prototype computer chips, more practical as a mass-production technique.  |
| Posted: 30 Jun 2011 08:15 AM PDT The European Space Agency's Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein. It has shown that any underlying quantum 'graininess' of space must be at much smaller scales than previously predicted.  |
| 'Dirty hack' restores Cluster mission from near loss Posted: 30 Jun 2011 08:15 AM PDT Using ingenuity and an unorthodox 'dirty hack', the European Space Agency has recovered the four-satellite Cluster mission from near loss. The drama began in March, when a crucial science package stopped responding to commands -- one of a mission controller's worst fears.  |
| Posted: 30 Jun 2011 06:18 AM PDT By tracking atmospheric features on Neptune, a planetary scientist has accurately determined the planet's rotation, a feat that had not been previously achieved for any of the gas planets in our solar system except Jupiter.  |
| Astronomers reveal a cosmic 'axis of evil' Posted: 30 Jun 2011 04:34 AM PDT Astronomers are puzzled by the announcement that the masses of the largest objects in the universe appear to depend on which method is used to weigh them.  |
| Squeezed light from single atoms Posted: 30 Jun 2011 04:33 AM PDT Scientists have generated amplitude-squeezed light fields using single atoms trapped inside optical cavities.  |
